Summary of change:
Today i experienced a weird issue. Parts that are involved: Kit 1: * VEMS ECU 672 + WBO2 sensor A,reads perfectly from lambda 0.71 to 1.2 ,whatever. ** With what calibration value ? (I assume it was calibrated in free air) Kit 2: Round (serialnr?) which also reads fine with its WBO2 sensor B. Problem: * i removed the VEMS ECU,and installed the Round into the car, so Round is now connected to WBO2 sensor A. ** what is the rcal resistance of sensor-A ? (between pin2 and pin6) ** round with sensor-A will not read richer than 0.92 ** did you see this on the round (maybe reading something different or using a multiplier?) or on the connected notebook in megatune / vemstune ? Any help appriciated. Thanks,Peter * When you used swapped to sensor-B and used it with round, did it work OK ? * what are the pump_pwzero and nernstdc_target settings inside the round ? * is the pump- of the round around 4V as it should ? * is the LSU4 sensor +12V supply coming from the round ? Did you measure it?
